Reasons Why Your Shoulders Click, Pop, Grind, and Crack

Key Takeaway

The shoulder popping or cracking sound, also known as crepitus, can occur due to various reasons, ranging from non-threatening causes like gas release in joints to underlying conditions like bursitis, fractures, labral tears, osteochondroma, or osteoarthritis. While occasional popping without pain may not be concerning, persistent or painful cracking should be evaluated by a healthcare professional.

Summary

• Crepitus (cracking) in the shoulder joint does not always indicate a problem and can occur even when the tendons and bones are working together correctly.
• However, if cracking is accompanied by pain or occurs after an injury, it may signify an underlying muscle strain, tear, or fracture that requires medical attention.
• Potential causes of shoulder popping or cracking include:
  • Scapulothoracic bursitis (inflammation of fluid-filled sacs between bone and soft tissue)
  • Malunion of fractures of the scapula or ribs (improper healing of fractures causing bone ridges)
  • Labral tears (tears in the cartilage structure within the shoulder socket)
  • Osteochondroma (harmless bone growths)
  • Cavitation (release of gas bubbles from joints)
  • Osteoarthritis (breakdown of cartilage leading to bone-on-bone contact)
• Treatment options may include corticosteroid injections, anti-inflammatory medications, physical therapy, chiropractic adjustment, massage therapy, or over-the-counter pain relievers, depending on the underlying cause.
• If shoulder popping is accompanied by redness, swelling, warmth, or persistent discomfort during daily activities, it is advisable to consult a healthcare professional for proper evaluation and treatment.

Decoding the Cracking Sounds in Your Shoulder

Have you ever raised your arm or moved your shoulder in a certain way and heard a distinct popping or cracking sound? While this audible phenomenon, known as crepitus, can be unsettling, it’s not always a cause for concern. However, understanding the potential causes behind this noise can help you determine when it’s time to seek medical attention.

What Causes Shoulder Popping or Cracking?

The shoulder joint is a complex structure composed of bones, muscles, tendons, and cartilage, all working together to facilitate a wide range of motion. When these components move against each other, it can sometimes produce cracking or popping sounds. Here are some common causes of shoulder crepitus:

Scapulothoracic Bursitis

Bursae are small, fluid-filled sacs that cushion the areas where muscles, tendons, and bones rub together. When these bursae become inflamed, a condition known as bursitis, it can cause a painful popping or snapping sensation, particularly when moving your arms in various directions.

Malunion of Fractures

If you’ve suffered a shoulder fracture in the past, even if it has healed, the bones may not have fused back together perfectly. This can create bony ridges or protrusions that can catch or rub against the surrounding muscles and tendons, causing an audible popping or grinding sound.

Labral Tears

The labrum is a ring of cartilage that lines the shoulder socket, helping to stabilize the joint. Injuries or overuse can cause the labrum to tear, leading to pain and a grinding or popping sensation with arm movements.

Osteochondroma

These benign bone growths can develop on the shoulder blade or ribs, creating an obstruction that rubs against surrounding tissues when the shoulder moves, resulting in a popping or cracking noise.

Cavitation

Sometimes, the popping sound you hear is simply caused by the release of gas bubbles within the joint, a phenomenon known as cavitation. This is similar to the noise you hear when cracking your knuckles and is generally harmless.

Osteoarthritis

As the cartilage that cushions the joints breaks down due to age or injury, the bones can begin to grind against each other. This can lead to a grating or cracking sound in the shoulder, which is a common symptom of osteoarthritis.

When Should You Seek Medical Attention?

While an occasional pop or crack in the shoulder may not be cause for concern, there are certain situations where it’s advisable to consult a healthcare professional:

1. Persistent Pain: If the popping or cracking is accompanied by persistent pain, swelling, or limited range of motion, it could indicate an underlying injury or condition that requires medical attention.
2. Recent Injury: If the shoulder popping or cracking started after a recent injury, such as a fall or impact, it’s essential to get it evaluated by a doctor to rule out any fractures, dislocations, or soft tissue damage.
3. Interference with Daily Activities: If the shoulder noise is severe enough to interfere with your daily activities or sleep, it’s time to seek medical advice.
4. Accompanying Symptoms: If the shoulder popping is accompanied by redness, warmth, or other concerning symptoms, it could be a sign of an infection or more serious condition that requires prompt treatment.

Treatment Options

The treatment for shoulder popping or cracking will depend on the underlying cause. In some cases, home remedies like rest, ice application, and over-the-counter pain medication may be sufficient. However, in other instances, more extensive treatment may be necessary, such as:

• Physical Therapy: A physical therapist can design an exercise program to strengthen the muscles around the shoulder joint and improve flexibility, reducing the risk of further injury or discomfort.
• Corticosteroid Injections: For conditions like bursitis or tendinitis, corticosteroid injections can help reduce inflammation and alleviate pain.
• Anti-inflammatory Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) can help manage pain and inflammation associated with various shoulder conditions.
• Chiropractic Adjustments: In some cases, a chiropractor may be able to realign the bones and tissues in the shoulder area, potentially reducing popping or cracking sounds.
• Surgery: In severe cases, such as labral tears or advanced osteoarthritis, surgical intervention may be necessary to repair or replace damaged structures.

Prevention and Self-Care

While not all shoulder popping or cracking can be prevented, there are some steps you can take to minimize the risk of developing more serious issues:

• Maintain Good Posture: Poor posture can put unnecessary strain on the shoulder joints, increasing the likelihood of popping or cracking sounds.
• Warm Up Before Exercise: Properly warming up your muscles and joints before engaging in physical activity can help reduce the risk of injury and discomfort.
• Strengthen Shoulder Muscles: Incorporating shoulder exercises into your routine can help support the joint and improve overall stability.
• Use Proper Form: When lifting weights or performing other exercises, use proper form to avoid putting excessive strain on your shoulders.
• Apply Ice or Heat: After strenuous activity or if you experience discomfort, applying ice or heat can help reduce inflammation and promote healing.

Conclusion

Shoulder popping or cracking is a common occurrence that can have various underlying causes, some benign and others more concerning. While occasional popping without pain may not be a cause for alarm, persistent or severe cases should be evaluated by a healthcare professional. By understanding the potential causes and taking preventive measures, you can help keep your shoulders healthy and minimize discomfort.
